Washington judge orders Kalshi to restrict prediction markets statewide
The court mandated the company to halt betting-like contracts across the state.
1Legal blow to Kalshi
Washington State Superior Court Judge John McHale updated the preliminary injunction against Kalshi's prediction market platform on August 12. The ruling requires the company to stop Washington residents from purchasing contracts linked to sports, elections, politics, and other topics. The judge determined the platform violated state gambling and consumer protection laws. Attorney General Nick Brown called this decision 'the first step in holding Kalshi accountable for violating Washington laws.'
2Questionable contracts
On Kalshi, users buy 'yes' or 'no' contracts predicting future event outcomes. Winning contracts pay out while losers forfeit their wagers, with the platform taking transaction fees. Washington authorities argue this model constitutes gambling. AG Brown noted the platform promoted betting on controversial topics including measles cases, child trafficking hearings, and natural disasters.
3Tight deadlines
The court ordered Kalshi to implement IP-based geofencing by August 19. By September 2, it must activate a multi-source GeoComply system to block physical users in Washington from purchasing restricted contracts. Users can still close existing positions. Missing the September 2 deadline will cost the company $120,000 daily unless it submits a sworn affidavit explaining the delay.
4Banned categories
Restrictions cover sports, elections, politics, entertainment, culture, technology, science, and 'mention' contracts based on specific words/phrases. Commodities, climate, economics, and finance contracts remain unrestricted. Kalshi must also stop advertising prohibited products to Washington residents.
5Legal battle
Kalshi moved the March lawsuit to federal court, describing itself as a CFTC-regulated derivatives exchange. After remand, the company sought federal intervention during its May appeal, which Judge McHale rejected. The order states 'Gambling and futures market regulations are distinct fields' and concludes the Commodity Exchange Act doesn't preempt Washington's gambling laws.
6Consumer protection
The court ruled Kalshi's 'legal betting' ads in Washington were misleading. Judge McHale wrote 'The public interest and potential consumer harm from Kalshi's continued gambling operations outweigh harm to the company.' Kalshi must preserve Washington customer records (account activity, communications, location data, marketing info). Users can still withdraw funds and close accounts.
7Industry impact
This ruling sets a significant precedent for prediction markets. The Washington State Gambling Commission declared event-based contracts unauthorized in December 2025, noting legal sports betting remained available only at tribal casinos. If Kalshi appeals, prolonged litigation could spark similar legal challenges in other states.
8Regulatory call
The Kalshi case highlights tensions between financial innovation and consumer protection regulations. Judge McHale's decision shows state laws can override federal frameworks. Other fintech platforms may need to reassess state-level legal risks for similar business models. Experts emphasize the urgent need for clear federal regulations governing prediction markets.
